Survey costs

Is there a national price for the damp investigation a home survey has asked you to commission?

There is not a national price. When the home survey tells you to commission a damp investigation, it is sending you to another firm. It is not quoting that firm's fee. Moisture meters, salts tests, opening finishes and a written opinion are priced by the specialist who will do them. Compare those scopes before you compare the fees. A higher fee does not prove the original survey was wrong.

Last reviewed 24 October 2026. Written for buyers in England and Wales unless this answer says otherwise. No named surveyor has signed this page. It is general guidance, not a report on your house, and not legal advice.

What is the fuller explanation?

Surveyors recommend further investigation when a visual visit cannot explain staining, salts or a high meter reading. That recommendation is a limit on the first inspection, not a price list. One specialist may offer a short visit. Another may include sampling, a longer report, or a return after drying. Those are different products. RICS has not set a single fee that both must charge, and the home-survey guidance does not contain a damp tariff you can cite in a complaint about the specialist's invoice.

Read what each quote includes before you decide one firm is expensive. Travel, the number of rooms, whether furniture must move, and whether they will comment on plumbing leaks as well as rising moisture all belong in the scope. The original report can tell you why a further visit was advised. It cannot tell you what that visit should cost. Pay the specialist under their own terms, and do not deduct an invented damp fee from the purchase price as if the survey had calculated one.

What should you ask your surveyor?

What exactly should the damp firm investigate, based on what you saw?
Which readings or stains are outside a visual home survey?
Will you be commenting on their report, or is that a separate instruction?

What are the typical next steps?

Get the specialist's scope in writing before comparing fees.
Do not treat the recommendation as a fixed call-out price.
Keep the damp invoice separate from the survey invoice.

Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

Also asked about this

Does a meter reading in the survey already include the specialist's tests?

No. A home survey look is not the further investigation it has asked you to commission.

If two damp quotes differ, which one has RICS chosen?

Neither. RICS does not pick the specialist's fee. You compare the work each firm has described.
